Description
  • Principy systémového návrhu a architektury programů distribuovaného řídicího počítač trakčního vozidla. Systémový návrh bere v úvahu funkčnost, spolehlivost a udržovatelnost. Zvláštní důraz se klade na optimální rozdělení systémových funkcí v distribuovaném počítači za účele minimalizace režie komunikace a minimalizace funkcí realizovaných v hardware. Vozidlový počítač je tvořen uzly lokální počítačové sítě. Přístup na sběrnici typu master-slave. Komunikační služby jsou jednotné pro všechny uzly. Režie komunikace minimalizována použitím DMA. Uživatelské úkoly jsou plánovány preemptivním RT operačním systémem s dynamickým plánováním. V uzlech s vysokými požadavky na výkon počítače je použita statická exekutiva. (cs)
  • The principles of system design and software architecture of the distributed network control computer (DNCC) of a traction vehicle are presented. The system design is based on such criteria as functionality, reliability and maintainability. To reach these properties special emphasis is placed on correct and optimal system functions partition among distributed computer nodes to be minimized the overall communication overhead and on minimizing the hardware parts of the system and moving maximum of functions into the software. As an example of such design task the DNCC of an electric locomotive is introduced. The vehicle DNCC is organized as a local computer network with master-slave node access method with dual serial bus. The network communication services are uniformly used in all nodes to support reliable transfer of the process data. The communication overhead is minimized using exclusively DMA transfer method.
